WELDING OPERATIONS
SEQUENCE OF OPERATION
Wire Loading
Refer to Figure B.2 AND B3.
The machine power switch should be turned to the
OFF (
“ O ” ) position before working inside the wire feed
enclosure.
The machine is shipped from the factory ready to feed
4
” (100 mm) diameter spools. A 4" (100 mm) diameter
spool is mounted directly on the 5/8" (16 mm) diame-
ter spindle that has a built-in adjustable friction brake
to prevent overrun of the spool and excess slack in
the wire. The wing nut at the end of the shaft is used
to adjust the tension on the wire spool.
FIGURE B.2
To use 8" (200 mm) diameter spools, the 2" (51 mm)
diameter M15445 spindle must be used. Remove the
spacer and wing nut at the end of the shaft. Insert
spindle as shown in figure B.3. Reattach spacer and
wing nut.
Note: When loading and removing the 8 ” Spools
make sure that the wing nut (inside the wire spool
spindle hub) is turned 90
° from the wire spool spindle
locking tab. If the wing nut is positioned in line with the
locking tab, the tab cannot be depressed to load or
unload the wire spool.
Make certain the start end of the wire, which may pro-
trude through the side of the spool, does not contact
any metallic case parts.
